You ideally want to produce clean hydrogen fuel using clean sources, and Dutch researchers have taken a big step toward making that a practical reality. They've built a solar cell that uses a grid of gallium phosphide nanowires to make hydrogen gas from water. The approach gets a useful yield of a...

Thanks to the efforts of a North Carolina-based company, solar panels are about to get a lot more efficient. Semprius produces the collection devices by stacking materials on top of each other in order to catch more frequencies of light. In the process, cell stacking boosted efficiency to around 4...

Solar power cells need to stay relatively cool for the sake of both efficiency and longevity, but active cooling (like ventilation) isn't practical; it's expensive, and may block the very rays the cells are supposed to collect. To tackle this problem, Stanford University researchers have created a...

It's tough to build solar cells that capture both heat and light -- most of these multi-talented devices can't trap more than one percent of the energy they receive. However, MIT has just blown past that limitation with a prototype chip that absorbs warmth through an outer layer of carbon nanotub...

Harnessing the awesome power of the Sun isn't just dependent on the efficiency of solar cells, but also on making them affordable. Current techniques aren't exactly cheap, but researchers from Stanford University think they've made a bit of a breakthrough by producing a relatively inexpensive phot...

We see a lot of sleek-looking technology pass through our doors, but it's rare that the inventions could be called beautiful by those who aren't immersed in the gadget world. We'd venture that North Carolina State University might have crossed the divide by creating an energy storage technology th...

Generating solar power from the infrared spectrum, or even nearby frequencies, has proven difficult in spite of a quarter of the Sun's energy passing through those wavelengths. The Fraunhofer Institute for Telecommunications may have jumped that hurdle to efficiency through sulfur -- one of the ve...

Eking out more power from solar cells is an ongoing challenge for scientists, and now architect Andr&eacute; Broessel has developed a spherical glass energy generator that's said to improve efficiency by 35 percent. Acting as a lens, the rig's large water-filled orb concentrates diffused daylight...

Harnessing the power of the sun is a tricky business, but even the past few weeks have seen some interesting developments in the field. In this latest installment, researchers from the Lawrence Berkeley National Laboratory and the University of California have figured out a way of making solar cel...

Solar cell development is typically a small numbers game, and a group of researchers at the University of Toronto have managed to eke out a few more percentage points in efficiency with a new record-breaking cell. Setting a high mark for this type of cell, the team's Colloidal Quantum Dot (CQD) fi...

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. The Olympic flame completed its tour through the UK this week as the 2012 Summer Games officially kicked off on Friday, and all eyes have been on London eve...

Transparent photovoltaics have yet to grace the face of your smartphone, but don't give up hope -- UCLA researchers are working on a new see-through solar cell that's showing potential. Using a new type of polymer solar cell, the team has been able to build a device that converts infrared light in...
